The average cost of replacing fuel injectors in an Infiniti G37 is between $494 and $650
Fuel injectors regulate the amount of pressurised fuel used for each engine cycle. There is one injector per cylinder in an engine. Each time an intake stroke occurs in the engine, the vehicle's computer will send a signal to the fuel injectors, requesting they spray fuel. For heavy acceleration, the duration of the fuel spraying will be longer than if the engine were idling. When a fuel injector fails or clogs, engine power is reduced and misfires will occur.
To replace a fuel injector, the intake manifold must typically be removed to access and replace the fuel injectors. The average cost for a fuel pump replacement in an Infiniti G37 is between $759 and $779.

Fuel injectors regulate the amount of pressurised fuel used for each engine cycle
The average cost for a Fuel Injector Replacement for an Infiniti G37 is between $494 and $650, but can vary from car to car.
Fuel injectors are electronically controlled valves. They are supplied with pressurised fuel by the fuel pump in your car, and they are capable of opening and closing many times per second. When the injector is energised, an electromagnet moves a plunger that opens the valve, allowing the pressurised fuel to squirt out through a tiny nozzle. The nozzle is designed to atomise the fuel, making it as fine a mist as possible so that it can burn easily. The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open. This is called the pulse width, and it is controlled by the ECU. The ECU uses information about the mass of air entering the engine and the amount of oxygen in the exhaust to fine-tune the fuel consumption and delivery so that the air-to-fuel ratio is just right.

When a fuel injector fails or clogs, engine power is reduced and misfires will occur
The average cost for a fuel injector replacement for an Infiniti G37 is between $494 and $650, but this can vary from car to car.
A restriction of 8-10% on a single fuel injector can be enough to cause a misfire. When this occurs, unburnt oxygen enters the exhaust and makes the O2 sensor read lean. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes. The most common fault codes associated with a clogged fuel injector are P0171 and P0174, which indicates the engine controller is seeing a lean condition. One of the obvious symptoms of a clogged fuel injector is the lighting up of the "Check Engine" light in your dashboard.
If the fuel injector is clogged, the fuel supply will be irregular too. When the fuel level fluctuates drastically, the high and low rpm's will cause the engine to move in surges rather than slow and gradual movements. If a clogged fuel injector continually struggles to disperse fuel to the engine, a time will come when it misses the fuel supply completely and the engine will misfire. The misfire will easily be felt while driving, and often requires immediate repair by trained automotive repair specialists.

Sugar in a gas tank can cause damage to fuel injectors
The average cost for a fuel injector replacement in a 2009 Infiniti G37 is between $494 and $650, but this can vary from car to car.
Sugar in a gas tank can cause serious damage to fuel injectors. When sugar is introduced into a gas tank, it can crystallize and form a sticky residue that clogs fuel lines, injectors, and other important components of the engine. This can lead to poor engine performance, decreased fuel efficiency, and even complete engine failure if not addressed promptly. The sugar can mix with the fuel and form a thick, sticky substance that can block fuel filters, injectors, and other fuel system components. This damage can result in unusual sounds, such as sputtering, knocking, or rattling. In some cases, the damage caused by sugar in a gas tank may be severe enough that your vehicle needs to be towed to a repair shop.
